flolall whom it concern:

Be it known that we, EDWARD CUNNIFF,

ALFRED Connnian, and OMAR Benson, citi- Zens of the United States, and residents of New Bedford, county of Bristol, State of Massachusetts, have invented an Improve rnent in Tip-Supports for Automatic Filling- Replenishing Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on. the drawing representing like parts.

In automatic looms-of the Northrop type a filling-carrier is engaged by a transferrer and removed automaticallv from a feeder or hopper and inserted in the shuttle, as in United States Patent No. 529,940 granted to J' H. Northro November 27., 1894, the base and ti of t e filling-carrier being engagcd by the transferring instrumentality. A tip-support is-also provided, constructed as a pivotally mounted and yieldin ly-controlled metallic finger to' extend eneath and guide the tip of the fiilin -carrier during transfer thereof to the shutt e.

- It has been found in practice that at times the filling will rub over or ,be pinched between the tip of the filling-carrier and the contacting face of the tip-support, so that the filling will be broken, artrcularly when very fine filling is used, and also when metal cop-skewers are used.

Our present invention has for its object the production of means to prevent the engagement of the filling with the metal of the tip-support, and to that end we provide the engaging face of. the latter with a non-metallic facing or contact piece, preferably leather, such facmg or contact piece being held on the tip-sup ort in such manner that when worn it can e readily removed and a new facing substituted.

Figure 1 is a transverse section of a sulficient portion of the fillin replenishing mechanism of an automatic oom, showing the tip-support embodying one form of our invention; Fig. 2 is an enlarged detail in side elevation of the tip-support and its non motallic facing or contact piece.

The filling-feeder, partly shown at E, Fig. 1, to contain a supply of filling-carriers l), the transferrer f" mounted to rock on the fixed stud f and adapted to engage the head or butt f the filling-carrier, the laterally extends d arm 21 on the transferrer and havingclip the downtiirned end 22 to d the filling-carrier; the arrnf g to the stud f and the tip-support ivotaily mounted on said arm at f and having its free end 25 downwardly curved, may be and are all substantially as in United States Patent No. 720,189 granted to Stirn n Februarv 10, 1903, the tip-support being yieldingly-controlled and normally held with its tail t against the stop 5 on the arm f At the time of transfer the tip-support extends beneath and guides the tip of the filling-carrier as it is transferred ironi the feeder F and inserted in the shuttle S, Fig. 1, and at such time if the filling is caught between the upper or contacting face of the curved end i of the tip-su iport and the tip of the filling-carrier the filling is apt to be broken. In accordance with our present invention, and to prevent such engagement of the filling with the metal of the tip-support,

We mount on the upper face of the latter a contact-piece or facing 1, which may be of any suitable non-metallic material. Prefer ably we use a strip of leather, bent "to the contour of the upper face of the tipsupport and curled or bent over its exti inity, at 2, see Fig 2, the-contact-piecc being held securely in place by a metal clip 3 engaging and overl ing the same at its upper end and connects with the tip-support y a scr'ewbolt 4, or other suitable fastener, extended through the facing into the body of the tipsupport. The length of the clip 3 is such that it cannot engage the fillingmarrier or its filling, the entire face or portion of the tip support which cooperates with the tip of the filling-carrier being covered by the contactmoved by detaching the clip and i toning 3, andapplying a new racing, m r-li the and fastening are replaced and the fasten in -set up.

W011 leather is used for the facing 'i' siliency thereof holds the free portion thereof against the tip-support beyond the clip, and

the bend at 2 catches onto the extremity of i then m and a holder )zu-tl over] 'in r 11, 1,) in the tap-support and aids in holding the mung the eevvm: to SC "ure the same 111 place. 1n proper position. in toslimm'iy v mreof, We have signed our 15 Havm full described our invention.
